Description

The invention relates to a vehicle roof, in particular for motor vehicles, according to the generic terms of the next ordered claims 1 and 2.

Preferred areas of application of the invention are vehicle roofs modules finished separately from the vehicle body and only on the assembly line in the automobile factory with the Fahr be assembled body. Such vehicle roof modules are particularly pleased because of the considerable shortening the assembly time on the assembly line of increasing importance. Are such vehicle roof modules with an integrated Sunroof unit equipped, like that on the vehicle roof is the case according to claim 2, the separate manufacturer opens the advantageous possibility of a functional check of the preassembled sunroof unit even before the Roof module with the body.

In such a known vehicle roof (DE 197 09 016 A1) either the headliner is an inseparable part of the the inner skin of the roof foam, if no sliding roof unit is provided, or the headlining is on the Sunroof frame attached when a sunroof unit in front is seen. In any case, there is one in both embodiments Interchangeability of the headlining is not provided, but what may be desirable for various reasons. So could the headlining to different interior of the Vehicle can be adapted without different complete roof modules must be kept ready. Can too the interchangeability of a damaged or soiled Headliner may be desirable without the complete Roof module is to be removed.  

According to a unpublished proposal for a derar term vehicle roof (DE 199 47 238.6) is that as separate Part made of foam plastic pre-shaped headlining on his Provide the top with locking elements that fit perfectly complementary locking elements attached to the inner shell are releasably locked. Is the vehicle roof with a sliding roof unit is equipped, according to this suggestion Provide headlining on its top with locking elements that with a fitting fit on the sunroof frame complementary locking elements are releasably locked. The Verra stung enables a damage-free acceptance of the respective towards the headliner by releasing the catch. In this way not only an exchange of the headlining is made possible The roof module can also initially be handled without a headlining what makes it easier to attach it to the vehicle body tert. On the roof module can then be in the decorative off formation of its lower surface on the interior of the Vehicle-coordinated headlining can be installed.

The invention has for its object in a with or a vehicle roof without a sliding roof unit to provide sky that can be assembled in a further way and is interchangeable.

Use here alone or in combinations of words The term "sunroof" is intended for the purposes of this not only include such constructions according to the invention, where the lid after lowering its rear edge Clear the roof opening under the rear fixed roof area is movable, but also sliding sunroofs, where the lid also starts from its closed position a pivot axis provided near its front edge be pivoted to the exhibition over the fixed roof area can. Also show hinged ventilation flaps at the front bare lids and so-called top ridges, where the lid is partially released after lifting its rear edge  ver the roof opening over the rear fixed roof area is slidable, should be included. The same applies for roof constructions with several lids. In principle applies for all constructions where one is under the fixed Roof surface attached sunroof frame is present.

The object is achieved by the features of independent claims 1 and 2 solved. Advantageous Wei Further training results from the subclaims and are also described below.

Both embodiments specified in claims 1 and 2 is common that the respective headliner on its upper side with rail-like first guide elements that go have cut sliding surfaces, is provided. this first guide elements are rail-like second guide elements that also have undercut sliding surfaces zen, complementarily assigned. Correspond to the vehicle roof Chend claim 1 are the second guide elements on the Inner shell arranged while according to the vehicle roof Claim 2 the second guide elements on the sunroof frame are provided. Both configurations are in turn common sam that for fastening the headlining to the inner shell or on the sunroof frame on the first guide elements the second guide elements with their respective rear cut sliding surfaces engaging up to a defined Relative position of the inner shell or sunroof frame and The headlining is pushed in parallel. By diff Exercise in the opposite direction can attach the headlining can be canceled just as easily.

The rail-like first guide elements are pending the headliner up, and the second guide elements are each from the inner shell or the sunroof frame down and are from short Profilab cut formed. These are at each of their locations  provided in pairs, both with respect to the first Guide elements with each other and the second guide element elements with each other as well as with regard to the assignment of the first to the second guide elements, d. H. the first guide tion elements and the second guide elements form on each Place of attachment one pair each, but each pair from first Guiding elements form at the location in question the associated pair of second guide elements in turn a few.

The rail-like first guide elements and the rails like second guide elements are according to claim 4 preferably each formed from angled profile sections, the first guide elements with their to the headliner parallel legs point in opposite directions, while the second guide elements with their to the inner shell or legs parallel to the sunroof frame are swept. In this way it happens when the first guide elements on the second guide elements the headliner assembly for a positive engagement of the Guide elements in which the undercuts are indicated arranged sliding surfaces are in a flat system. A ver comparable positive engagement between the first and the second guide elements can also be achieved if the respective undercut sliding surfaces like a Intervene dovetail joint.

In a first embodiment of the invention according to claim 5 are the first and second guide members on each type Location in pairs parallel to each other and at all locations locations parallel to each other. Have here that is, all guide elements are aligned parallel to one another direction of the slide-open direction when installing the headliner or the direction of removal when removing the headlining equivalent. For an exact fixation between the headliner mel and the inner shell or the sunroof frame to achieve  is provided according to claim 6 that to which he Most or the second guide elements attached stops are, which limit the deferment path.

A second embodiment of the invention provides according to claim 7 before that the first and second guide members on each Place of installation in the same direction as the cover Exercise with respect to assigned areas in pairs are arranged in a transitory manner, d. H. on each pair of the first feet tion elements and on each pair of the second guide elements the guide elements close the same angle like an arrow on. When attaching the headliner is its sliding path in the desired relative position between the headlining and the Inner shell or the sunroof frame through the stack limited the assigned areas.

According to claim 8, the first guide elements are advantageous from the foam plastic of the headliner itself and the two guiding elements made of the foam plastic of the inner shell itself and thus formed in one piece. If the vehicle roof is equipped with a sliding roof unit, the Arrangement according to claim 9 can be made so that the first guide elements made of the foam plastic of the Dachhim mels themselves and are thus formed in one piece, while the second guide elements as profile sections of the sliding roof frame or befe as separate parts are steady.

Alternatively, the training according to claim 10 also be done so that the first guide elements and / or second guide elements on the inner shell than originally separate profile sections by foaming in the plastic of the Headliner and / or fixed in the plastic of the inner shell are.

FIGS. 2 to 4 and 8 fragmentary vehicle roof module, each mounted headliners.

In Fig. 2, a roof module 1 is shown in which a rigid roof skin 2 , which can be formed from a deep-drawn sheet metal, for example aluminum sheet, or a vacuum-formed plastic film, is provided on its inner surface with a foamed inner shell 3 . Suitable materials for the inner shell 3 are rigid foam plastics based on PUR, which can be reinforced by the plastic prior to foaming an incorporated fiber material, for example glass fiber sections. But also in the foam form inlaid fabrics, knitted fabrics, nonwovens u. The like. Are suitable as reinforcement. By foaming the reinforced inner shell 3 , which extends to an edge fold 4 of the roof skin 2 , a sandwich-like composite roof module with high dimensional stability and strength is created. All the inner contours of the inner shell 3, including the guide elements to be described, are formed during the foaming process by appropriate shaping of the foam shape. Thus, the inner shell 3 is in its border area on the edge fold 4 , with which it is placed on a body frame 5 , with a circumferentially molded receiving groove 6 , in which a roof module 1 sealing against the body frame 5 and sealing BEFE increasing adhesive bead 7 is received ,

The roof module 1 designed in this way is assigned a separately produced roof liner 8 , which in the exemplary embodiment shown in FIG. 2 is preformed from a foam plastic and has areas covering the body frame 5 . The connection of these areas with the body frame 5 can take over a connecting piping 9 , which can also have a hollow chamber section for sealing the adjacent vehicle door (not shown) with respect to the body frame 5 . The headliner 8 can also be formed from a foamed plastic, for example based on PUR. Furthermore, the foam plastic of the headliner 8 can be reinforced in the manner described with respect to the inner shell 3 . On its lower surface, the headliner 8 can be designed decoratively, for example it can be provided with a coating 10 made of textile material or a plastic film.

The roof liner 8 is provided on its upper side with rail-like first guide elements 11 which have undercut sliding surfaces 12 . The first guide elements 11 are complementarily formed rail-like second guide elements 13 on the inner shell 3 . These second guide elements 13 also have undercut sliding surfaces 14 . When installing the headliner 8 this is pushed in the vehicle longitudinal direction with its first guide elements 11 onto the second guide elements 13 of the inner shell 3 , the headliner 8 being essentially in the parallel position to the inner shell 3 . During the slide-on process, the respective undercut sliding surfaces 12 and 14 of the first guide elements 11 and the second guide elements 13 come into engagement. The slide-on process is finished as soon as a defined relative position of the inner shell 3 and headliner 8 is reached.

As shown in FIGS. 3 and 5 in conjunction with FIG. 2 show, the rail-like first and second guide elements 11, 13 are each formed of short profile portions and arranged in pairs. Arrangement pairs are provided at several spaced apart locations of the headliner 8 or the inner shell 3 . As shown in the example of the inner shell 3 according to FIG. 5, there may be four attachment locations 15 spaced apart from one another. The first guide elements 11 are provided at appropriate locations of the roof lining 8 .

The rail-like first guide elements 11 are formed at each of their attachment locations from pairs and mutually spaced angular sections, as shown in FIG. 2 in conjunction with FIG. 3. These angle profile sections are arranged with their legs 16 parallel to the headlining 8 pointing in opposite directions. As can also be seen from FIG. 2, the complementary rail-like second guide elements 13 are also formed from paired angular sections which are spaced apart from one another, but are turned toward one another with their legs 17 parallel to the inner shell 3 .

As can be seen from FIG. 3, the first and second guide elements 11 , 13 are arranged in pairs at each attachment location in parallel to one another and, moreover, are aligned parallel to one another with respect to all attachment locations, as is evident with respect to the second guide elements 13 from FIG. 5.

Stops 18 are attached to the first or the second guide elements 11 , 13 , but in the example shown to the second guide elements 13 . These stops are in the example ge drawn by projections 19 of the legs 17 gebil det, as shown in FIGS . 2, 3 and 5. In the BEFE stigung the headliner 8 on the inner shell 3, the stops 18 limit the sliding path of the headliner 8 when reaching the desired relative position between the Dachhim mel 8 and the inner shell 3rd Only when this fixed rela tive position is reached, the headlining 8 is connected via the connecting piping 9 to the body frame 5 .

In the second embodiment of the guide elements, which is shown in FIGS. 4 and 6, the first and the second guide elements 11 ', 13 ' at each of the four attachment locations 15 , for example, are coincident in the direction of the fastening displacement with respect to assigned surfaces, of which in Fig. 4 only the surfaces 20 on the first guide elements 11 'and the surfaces 21 on the second guide elements 13 ' are shown in pairs converging net. The arrangement is such that both the most guide elements 11 'and the second guide elements 13 ' are symmetrically provided on each of the mounting locations 15 with respect to a symmetrical axis 22 . The axes of symmetry 22 of the four mounting locations 15 in turn run parallel to one another. Due to these circumstances, when the headliner is attached to the inner shell 3 ', the sliding path of the headliner in the desired relative position between the headliner and the inner shell 3 ' is limited by the coincidence of the assigned surfaces 20 and 21 .

For the two previously described embodiments, the first guide elements 11 and 11 'are made of the foam plastic of the headliner 8 itself and the second guide elements 13 and 13 ' made of the foam plastic of the inner shell 3 and 3 'itself and thus in one piece shaped. The first guide elements 11 and 11 'on the headliner 8 and / or the second guide elements 13 and 13 ' on the inner shell 3 and 3 'can also be used as originally separate profile sections by foaming in the plastic of the roof lining 8 and / or Plastic of the inner shell 3 or 3 'BEFE Stigt (not shown).

In the game shown in FIGS. 7 and 8, the vehicle roof 23 , which has also been described as previously, can be designed as a roof module, which is intended for attachment to a body frame, equipped with a sliding roof unit. In the example shown, this sunroof unit includes a sunroof frame 25 which is firmly connected to the most roof skin 24 and on which guide rails 26 for guiding func ons and drive elements (not shown) for the sliding cover 27 are located. In the exemplary embodiment, the sliding cover 27 is a glass cover, but could also be formed in a known manner as a sheet metal cover. An inner shell made of plastic can also be foamed onto the inner surface of the roof skin 24 , as is indicated by a chain line in FIG. 8. FIGS. 7 and 8 show the sliding cover 27 in its closed position. The headliner 28 is releasably connected to the sliding roof frame 25 in a manner to be described in this embodiment.

The sunroof frame 25 is formed from an extruded aluminum profile, to which not only the guide rails 26 are formed in the example shown, but also projecting downward as profile sections of the sunroof frame 25 formed second guide elements 29th This guide elements 29 can also be formed as separate parts and attached in a suitable manner to the sunroof frame (not shown). The arrangement and function of the second guide elements 29 match the second guide elements 13 and 13 'of the above-described embodiments. They are also rail-like and have undercut sliding surfaces, as was described with reference to FIG. 2 with reference to the sliding surfaces 14 .

The headliner 28 is also preformed as a separate part made of foam plastic in this embodiment and provided on its top with rail-like first guide elements 30 . These guide elements also have cut sliding surfaces behind, as has been described with reference to FIG. 2 using the sliding surfaces 12 . As illustrated in FIG. 8, the first guide elements 30 and the second guide elements 29 are designed to be complementary. Also in this embodiment of the Dachhim are used to attach pushed mels 8 on the sliding roof frame 25, the first guide elements 30 on the second guide elements 29 with their respective undercut sliding surfaces engaging in a parallel position of the roof lining 28 to the sliding frame 25 until a defined fixed relative position of the sliding roof frame 25 and headliner 28 is reached. In the case of first and second guide elements 30 , 29 aligned parallel to one another, the defined relative position can be defined by stops, as was described with reference to FIGS. 3 and 5. The guide elements 29 and 30 can, however, also be converged to determine the defined relative position converging to one another, as has been described with reference to FIGS . 4 and 6, but then a one-piece extrusion formation of the guide elements 29 with the frame 25 is not is possible.

Fig. 8 shows that the first guide elements 30 are formed from the foam plastic of the headliner 28 itself and thus in one piece. However, in this example, the first guide elements can also be foamed as separate parts in the foam plastic of the headliner 28 for fastening them.

It is proposed to be especially for motor vehicles correct vehicle roof, especially one separate from the Body to be made and with the body frame too uniting roof module, which essentially consists of a rigid Roof skin, possibly an inner shell foamed thereon Foam plastic and a decorative headliner made of foam plastic is made. The roof module can be integrated Sunroof unit must be equipped. The peculiarity exists in that the headlining is made separately from the roof module and via complementary precisely fitting guide elements with the inner shell or, if necessary, with the sunroof frame of the Sunroof unit can be releasably engaged, d. H. is interchangeable.
